Police have confirmed a burnt-out vehicle found in bushland at Menai is linked to the body of a woman who was discovered nearby last month.
Police today confirmed the death was being treated as a homicide and the State Crime Command's Homicide Squad was leading the investigation.
Police discovered the vehicle last Monday, and have confirmed it was a short distance from where the body of Najma Carroll was located the previous week.
A NSW Police spokesman said Homicide Squad detectives and officers from Sutherland Shire Police Area Command recovered the burnt-out vehicle last Monday as part of ongoing inquiries into her suspicious death.
"The vehicle, linked to Ms Carroll, was discovered a short distance from where her body was located," the spokeswoman said.
"It was seized and taken from the site for forensic examination."
Strike Force Dalcassia has been formed to investigate the death.
Ms Carroll's body was found by a member of the public who was walking his dog in Sandy Point Quarry, off Heathcote Road, Menai, at about 5.15pm on Wednesday, July 29.
Police held a press conference the following day and identified the woman as Najma Carroll, 33.
Police confirmed a fire had been lit in the area where her body was found.
Sutherland Shire Police Area Command Acting Superintendent Steve Patton asked anyone who might have known Ms Carroll or had any information about her last movements to come forward.
Police were keen to speak with anyone who had frequented the area of bushland known as 'white rock' recently or who may have seen anything suspicious in the area.
Acting Superintendent Patton said Ms Carroll had not been reported missing before the discovery of her body.
He said she was in contact with her family "from time to time" and they were upset to learn of her death.
Ms Carroll was most recently known to reside in Sydney's inner west and was known to police.
The former Sydney Girls High School student was on the 2004 Higher School Certificate distinguished achiever's list and had studied at Sydney University.
A post on her Facebook page in October 2018 chillingly said: "Trust nobody".
Police have asked for anyone who can assist with inquiries to contact Crime Stoppers on 1800 333 000.
